<p><b>Syntax</b></p><blockquote>
Result = <font color="#006666"><b>IsWindow</b></font>(#Window)</blockquote>

</blockquote>
<b>Description</b><br><blockquote>

Tests if the given #Window number is a valid and correctly initialized, window. 

</blockquote><p><b>Parameters</b></p><blockquote>
<style type="text/css">
table.parameters { border-spacing: 0px; border-style: none; border-collapse: collapse; }
table.parameters td { border-width: 1px; padding: 6px; border-style: solid; border-color: gray; vertical-align: top; font-family:Arial; font-size:10pt; }
</style>
<table width="90%" class="parameters">
<tr><td width="10%"><i>#Window</i></td>
<td width="90%"> 
The window to use. 

</td></tr>
</table>
</blockquote><p><b>Return value</b></p><blockquote>

Returns nonzero if #Window is a valid window and zero otherwise. 

</blockquote><p><b>Remarks</b></p><blockquote>

This function is bulletproof and can be used with any value. If the 'Result' is not zero then the object is valid and 
initialized, otherwise it will equal zero. This is the correct way to ensure a window is ready to use.
